Glock Buffer

ABSTRACT

A method and apparatus providing for a buffer for the movement of pistol slide against the frame. Wherein said buffer system minimally diminishes the rebound of said pistol slide such that the pistol is still functional with respect to proper blowback operation. Wherein said buffer fits the form of frame and directs pressure from glide rod radially.

FIELD OF THE INVENTION

The application relates to a method and apparatus for protecting theinternals of a pistol from damage due to the movement of the handgunslide hitting the frame.

BACKGROUND OF THE INVENTION

1. Prior Art

During regular firing of a pistol, as the slide of the pistol movesforward it hits the frame of the pistol, causing damage to bothelements. The compression spring acts to buffer this impact bydecelerating the motion of the slide as it moves towards the frame.Shooters have utilized different options to internally buffer the frameand slide of a pistol to prevent wear as well as reduce recoil. Thesemethods involve utilizing compartments of compressible liquids, multiplespring setups, and frictional elements. These methods are flawed in thatthey often lead to unreliable setups that are prone to malfunctioning ordamage. Most stock pistols only use friction and the compression of onespring to stop and rebound the slide mechanism. This method isfunctional, but causes extreme stress on the internal elements of thepistol. Methods to reduce this stress have been used in the prior art,but often lead to a diminished or insufficient rebound of the slidemechanism. This diminished or insufficient rebound can cause problemswith the safety and/or accuracy of the weapon.

Presently, there exist certain buffer systems which use a flexible orcompressible material to form a buffer between the pistol frame andslide, but these are often not endurable because of the constant strainapplied to these systems which are inherently weak. Furthermore, thisstructural weakness is compounded by the configuration of these bufferswhich applies great pressure on certain parts of the buffer because thebuffers are flat while opposing a pointed frame edge. Another failure ofthese buffer systems is that they often break apart because the sliderod in the center applies pressure to the inner portion of the bufferopposite to pressure on the outer portion of the buffer applied by theframe. This type of buffer fails quickly because all pressure input istransferred axially, causing greater stress on the buffer.

There exists a need for an internal buffer system which reduces damageto the pistol slide and frame without leading to radically diminished orinsufficient rebounding of the pistol slide while increasing thedurability and effectiveness of the buffer system over present buffersystems.

2. Objects and Advantages

Accordingly, several objects and advantages of this invention are:

-   -   (a) To allow for greater protection of the pistol slide and        frame from excessive wear;    -   (b) To allow for reducing perceivable recoil;    -   (c) To allow for the compression spring to continue to perform        the function of rebounding the pistol slide.

Further objects and advantages of this invention will become apparentfrom a consideration of the drawings and ensuing description.

It is to be noted however, that the appended drawings illustrate only atypical embodiment of this invention and are therefore not to beconsidered limiting of its scope, for the invention may admit to otherequally effective embodiments.

DETAILED DESCRIPTION—FIGS. 1, 3, 4, 8

With reference now to the drawings, the preferred embodiment of theglock buffer according to the present invention is herein described. Ascan be seen in FIG. 1, according to certain embodiments of the priorart, compression spring 10 is coiled around compression rod 11.Compression spring 10 is uncompressed while the internals of pistol 30are not undergoing the stress of blowback operation.

As can be seen in FIG. 3, according to certain embodiments of thepresent invention, compression spring 10 is coiled around compressionrod 11. Buffer piece 20 circumscribes compression rod 11. Whencompression spring 10 is compressed during blowback operation, bufferpiece 20 is also compressed.

As can be seen in FIG. 4, according to certain embodiments of thepresent invention, compression spring 10 is coiled around compressionrod 11. Buffer piece 20 circumscribes compression rod 11.

As can be seen in FIG. 8, according to certain embodiments of thepresent invention, wings 21 of buffer piece 20 cause buffer piece 20 tofit to pistol frame 13.

The foregoing description of the invention has been presented forpurposes of illustration and description. It is not intended to beexhaustive or to limit the invention to the precise form disclosed, andother modifications and variations may be possible in light of the aboveteachings. The embodiment was chosen and described in order to bestexplain the principles of the invention and its practical application tothereby enable others skilled in the art to best utilize the inventionin various embodiments and various modifications as are suited to theparticular use contemplated. It is intended that the appended claims beconstrued to include other alternative embodiments of the inventionexcept insofar as limited by the prior art.

The invention may be embodied in other forms without departing from thespirit or essential characteristics thereof. The present embodiments aretherefore to be considered as illustrative and not restrictive, thescope of the invention being indicated by the appended claims ratherthan by the foregoing description, and all changes that come within themeaning and range of equivalency of the claims are therefore intended tobe embraced therein.

OPERATION—FIGS. 2, 3, 7

As can be seen in FIG. 2, according to certain embodiments of the priorart, as pistol 30 is affected by blowback and recoil, compression spring10 compresses. As blowback operation occurs compression spring 10compresses and pistol slide 12 hits frame 13 causing damage and wear tothe frame 13 and the pistol slide 12 each time the pistol 30 engages inblowback operation.

As can be seen in FIG. 3, according to certain embodiments of thepresent invention, as pistol 30 undergoes blowback operation,compression spring 10 compresses. As compression spring 10 compresses,compression spring 10 places stress on buffer piece 20. Buffer piece 20compresses as compression spring 10 presses on buffer piece 20, thusdampening and reducing the impact between the pistol slide 12 and pistolframe 13 which would otherwise damage the parts of pistol 30 overtime.Wings 21 of buffer piece 20 fit to frame 13 for a snug fit, increasingthe contact surface between buffer piece 20 and pistol frame 13 relativeto that of other buffer arrangements. This increased contact surfaceserves to lower the amount of pressure exerted on buffer piece 20,therefore reducing the damage to buffer piece 20 during blowbackoperation and increasing the durability of the buffer system of pistol30.

As can be seen in FIG. 7, according to certain embodiments of thepresent invention, as pistol 30 undergoes blowback operation,compression spring 10 compresses, placing stress on buffer piece 20. Asbuffer piece 20 is stressed, it deforms itself under pressure such thatthe flexible center 22 expands both axially and radially. As the bufferpiece's flexible center 22 expands radially, it pushes onto the outeredges of the buffer piece 20, thus ensuring the durability of the bufferpiece 20, and the buffer system of pistol 30 as a whole.
